ESA presents first LISA Pathfinder results [NOT TRANSLATED]
The mission
Launched in December 2015, LISA Pathfinder travelled to its operational orbit, 1.5 million km from Earth towards the Sun, where it started its scientific mission on 1 March. At the core of the spacecraft, two identical gold–platinum cubes, are being held in the most precise freefall ever produced in space.

Placing the test masses in a motion subject only to gravity is the challenging condition needed to build and operate a future space mission to observe gravitational waves. Predicted by Albert Einstein a century ago, gravitational waves are fluctuations in the fabric of spacetime, which were recently detected directly for the first time by the Laser Interferometer Gravitational-Wave Observatory.
Scientific activity
Over the first two months of scientific operations, the LISA Pathfinder team has performed a number of experiments on the test masses to prove the feasibility of gravitational wave observation from space. These results will be presented at the media briefing.
